Until recently, the complex frame components required for patio door designs were impossible to attain with fiberglass. But Milgard's R&D team changed all that by engineering French doors and French-style sliding patio door systems that are as attractive as they are weatherproof and durable. Their fiberglass components are up to three times stronger than wood and up to eight times stronger than vinyl. It's a difference you'll appreciate for a lifetime.
Our ENERGY STAR® qualified fiberglass patio doors ward off wind, snow and rain, year after year, without peeling, swelling, expanding, contracting, cracking or warping. They're impervious to cold, heat, insects, salt air and corrosion.
